（1）Chemical Composition

• Base: Copper (Cu)

Alloying elements: Beryllium (Be) content between 0.6% and 2.5%; may contain small amounts of cobalt (Co) and nickel (Ni) for additional strengthening.

• Comparable grades (international standards):

C17500 (Be 0.4–0.7%): High conductivity, moderate strength

C17200 (Be 1.7–2.5%): Ultra-high strength, moderate conductivity

（2）Physical Properties(Be 0.6–2.5%)

Density (g/cm³): 8.2–8.8

Melting Point (°C): 865–980 (varies with Be)

Electrical Conductivity (%IACS): 20–50 (higher Be = lower conductivity)

Thermal Conductivity (W/m·K): 100–200

Elastic Modulus (GPa): 110–130

（3）Mechanical Properties (Aged Condition)

• Be 0.6 (e.g., C17500)

Tensile Strength (MPa): 500–800

Yield Strength (MPa): 400–700

Elongation (%): 10–25

Hardness (HRC): 20–30

• Be 2.5 (e.g., C17200)

Tensile Strength (MPa): 1000–1400

Yield Strength (MPa): 900–1200

Elongation (%): 3–10

Hardness (HRC): 35–45

2. Core Advantages

（1）High Strength & Elasticity
Solution + aging heat treatment significantly increases strength, comparable to certain stainless steels but with lower weight. The high elastic limit makes it ideal for fatigue-resistant components like precision springs and contacts.

（2）Good Electrical & Thermal Conductivity
Lower Be content results in conductivity closer to pure copper. Suitable for high-current contacts and heat-dissipating electronic components.

（3）Wear & Corrosion Resistance
Excellent resistance to seawater, non-oxidizing acids, and general atmospheric corrosion. Non-magnetic—ideal for precision instruments.

（4）Non-sparking
Safe for use in explosive environments such as petrochemical and mining industries due to its non-sparking property.

3. Heat Treatment Process

The performance of beryllium copper is highly dependent on proper heat treatment:

（1）Solution Treatment
Heating to 900–980°C, followed by rapid water quenching to dissolve Be uniformly in Cu, producing a soft, workable state.

Tensile Strength (MPa): 500–600

Hardness (HRC): 15–20

Conductivity (%IACS): ~25

（2）Aging Treatment
Holding at 300–350°C for 2–4 hours precipitates fine Be phases, dramatically enhancing strength and hardness.

Tensile Strength (MPa): 1200–1400

Hardness (HRC): 38–45

Conductivity (%IACS): ~20

4. Typical Applications

（1）Electronics & Electrical
Connectors, relay contacts (high conductivity + elasticity, e.g., 5G RF connectors);

Battery clips, SIM sockets (excellent fatigue life).

（2）Industrial Tools
Non-sparking tools (safe for oil/mining);

precision mold inserts (high wear resistance).

（3）Aerospace & Defense
Aircraft bearings, missile guidance components (strength + corrosion resistance);

Satellite antenna springs (low expansion, high stiffness).

（4）High-End Consumer Goods
Watch balance springs (exceptional elasticity);

Golf club heads (strength + vibration dampening).

5. Safety Considerations

（1）Beryllium Dust Is Toxic
During machining, proper PPE (dust masks, wet cutting) is essential.

（2）Waste Management

Scrap must be handled by professionals to avoid environmental contamination.

6. FAQs

• Q1: Is TBe0.6-2.5 pure copper?

No, it is a beryllium copper alloy with 0.6%–2.5% Be—offering much higher strength and elasticity than pure copper.

• Q2: Can it replace stainless steel?

In high-conductivity + high-strength applications (e.g., electronic contacts), yes. However, for pure corrosion or ultra-high-temp resistance, stainless steel may be better.

7. Conclusion

Copper alloy TBe0.6-2.5 is a high-performance beryllium copper alloy that achieves an exceptional balance of strength, elasticity, and conductivity. By optimizing its Be content and heat treatment, it meets the stringent demands of electronic, defense, aerospace, and precision engineering sectors.
